Russia’s foreign minister says Iran and the West should stop behaving "like little children" and agree on where to hold talks on Tehran’s nuclear program.

Sergey Lavrov said Monday the essence of the talks was far more important than the atmosphere of any given town. He said Russia was hoping that "common sense would prevail and we will stop being capricious like little children."

Iran’s foreign minister blamed the West on Monday for holding up an agreement on the venue, striking back at the European Union, which accused Tehran of willfully delaying new nuclear talks with the six world powers.

Monday’s statements suggest no headway has been made on Iran’s proposal of Egypt as the site to renew dialogue, more than six months since the last round ended in stalemate.
